3.6 Dilution tests
There are 2 types of dilution measurement.
• Dilute and measure automatically by using [Dilution setting] in Mode function for administrator to
preset dilution factors for each test and sample type.
• Dilute and measure all items to be measured by setting a dilution factor for each sample at the
sample information registration screen.
The second method at the sample information registration screen is explained in this section.
IMPORTANT:
Bubbles may appear in the tip when diluting a plasma/serum sample more than 20 times or dilut-
ing a urine sample. If bubbles have formed during dilution, perform the measurement again from
the beginning.
NOTE
The results of measurements that included dilution are calculated automatically, so the re-
sults can be reported without adjustment.
NOTE
The maximum number of dilution measurements from one mixing cup well (hole) is three.
When the diluted sample in the well is insufficient, the analyzer automatically dilutes using
the next well.
NOTE
Do not dilute whole blood samples.
NOTE
The default dilution factors designated by the manufacturer are as follows: ISE urine tests:
2x; CRP tests: 21x.
Excluding ISE tests, the following section explains the relationships among the dilution fac-
tor configured for each sample at the sample information registration screen, the dilution
factor for each test configured by [Dilution setting] in Mode function for administrator, and
the dilution factor designated by the manufacturer. For ISE tests, the analyzer ignores the
dilution factors configured for each sample or each test and using default dilution factor of
the manufacturer.

(Example) With a CRP measurement with the dilution factor for each sample or test
configured to 3x, the analyzer will automatically dilute 63x.
NOTE
Setting positions of diluent in the diluent holder is set by each test using [Dilution setting] in
Mode function for administrator.
